Description
- The present invention relates to a razor knife. More particularly this invention concerns a deburring tool with a displaceable blade.
- A deburring knife as described in U.S. Pat. No. 5,598,634 has a body extending along an axis, having a front end, and having a rear end formed with an outer surface. A hollow handle fitted over the rear end has an inner surface confronting the outer surface of the body, and a blade is affixed to the handle front end. One of the surfaces is formed with a row of angularly extending and axially spaced holding ridges having outer edges and defining a row of axially spaced, radially open, and angularly extending holding grooves each extending relative to the axis over substantially less than 360°, and an axially extending ridge-free guide. The other of the surfaces is formed with a radially projecting holding ridge engageable in the grooves and on the guide. The guide and ridges are so dimensioned that when the other-surface ridge is aligned in the guide the handle can move axially on the body.
- Another knife is described in U.S. Pat. No. 5,168,630. It has a front end formed as a clamp in which a blade can be retained. The jaws of the clamp are connected to respective levers that are operable to spread these jaws and release the blade, so that it can be changed.
- Both these knives are relatively handy, yet they are of fairly complex construction. Both are comprised of quite a few separate parts that must be meticulously assembled and that therefore raise the manufacturing costs for the knife. This is a particular problem for a tool that can often be damaged in use, for instance by contact with solvents, and that must be replaced often.
- It is therefore an object of the present invention to provide an improved knife.
- Another object is the provision of such an improved knife which overcomes the above-given disadvantages, that is which is of simple and inexpensive construction, yet where changing the blade is a simple task.
- A further object is to provide such a knife which is of particularly slim construction.
- A knife has according to the invention an elongated body having a front end formed with a transversely directed holding face and a rear end. The body is formed between its ends with a transversely extending pivot and with a longitudinally extending guide. A blade can fit with the body holding face in a position projecting longitudinally forward from the body front end. A rocker carried on the pivot has forward of the pivot a holding face confronting the body holding face and rearward of the pivot a pair of transversely confronting inner faces. The rocker is pivotal between a closed position with its holding face closely juxtaposed with the body holding face and pressing the blade against the body holding face and an open position with its holding face spaced from the blade and body holding face. A slide has a front end engageable in the notch with the arm inner faces and is displaceable longitudinally along the guide in the body between one end position engaging one of the arm inner faces and pivoting the rocker into the open position and an opposite end position bearing on the other of the arm inner faces and holding the rocker in the closed position. A latch secured to the body bears on the slide in the one end position thereof.
- Such a knife is of extremely simple construction. It has four simple parts. The body and rocker, since they need to be fairly strong and durable, can be cast of light metal, and the slide and latch can be of plastic. Thus the knife can be made at very low cost, and its assembly and, if necessary, disassembly is a very simple operation requiring no tools. The blade is solidly locked in the closed position of the rocker so that the knife can be used to scrape, for instance as a deburring tool, without the blade coming loose. The pivotal action creates considerable clamping force, unlike the slide-type fit of the prior art.
- According to the invention the rocker has a pair of transversely spaced arms each forming a respective one of the inner faces and both projecting away from the pivot. One of the inner faces is formed with a wedge-shaped bump projecting transversely toward the other of the inner faces and bearing on the slide front end in the one end position thereof. The slide front end is transversely offset. Thus as it moves back an angled face on the offset end engages the bump and pivots the rocker into the open position. When moved forward, the slide engage the opposite face and forces the holding faces together on opposite sides of the blade. To this end the slide front end has a pair of transversely oppositely directed outer faces respective engageable with the inner faces of the rocker.
- The guides include at least one longitudinally extending ridge on the body. The slide is formed with a complementary longitudinally extending groove fitting with the ridge. Normally there are two such guide ridges and complementary grooves. Thus the slide is solidly mounted so that it can exert the necessary transverse force to hold the blade tightly, yet still moves easily longitudinally on the knife body.
- This slide has according to the invention an edge provided with grip formations projecting past the body. These formations are a plurality of longitudinally spaced and transversely extending ridges.
- In accordance with the invention the latch is basically J-shaped and body is formed at its rear end with a transversely projecting bridge to which the latch is clipped. Thus it is a very simple part.
- The knife blade is formed with a throughgoing hole, and one of the holding faces is formed with a transversely projecting pin fittable through the hole and the other of the holding faces is formed with a transversely open seat in which the pin is engageable in the closed position. This solidly locks the blade in place in the closed position of the rocker.
- The body is formed as a pair of parallel bars unitarily joined by front, middle, and rear bridges. The front bridge forms the body holding face, the middle bridge forms a pivot for the rocker, and the rear bridge carries the latch. Such construction is extremely durable, yet most of the outer surfaces of the knife are formed by the body. Normally according to the invention outer surfaces of the slide and rocker are flush with outer surfaces of the body in the closed position.
- The above and other objects, features, and advantages will become more readily apparent from the following description, reference being made to the accompanying drawing in which:
- FIG. 1 is a top view of the knife;
- FIG. 2 is a longitudinal section taken along line II-II of FIG. 1;
- FIG. 3 is a side view taken in the direction of arrow III of FIG. 1;
- FIG. 4 is a longitudinal section taken along line IV-IV of FIG. 3;
- FIGS. 5 and 6 are exploded perspective views taken in the direction of respective arrows V and VI of FIG. 4;
- FIGS. 7 and 7A are side and perspective top views of the rocker of the knife;
- FIGS. 8 and 8A are side and perspective top views of the slide of the knife; and
- FIGS. 9 and 9A are side and perspective top views of the latch of the knife.
- As seen in FIGS.1 to 4, a deburring tool or
knife 10 according to the invention has a body or handle 11, a rocker 12 (see also FIGS. 7 and 7A), a slide 13 (see also FIGS. 8 and 8A), a latch 14 (see also FIGS. 8 and 9A), and areplaceable blade 15. Theparts parts blade 15 is typically of steel. Thehandle 10 has a pair of smooth and outwardly convex outer faces 11 a and 11 b formed by a pair of side pieces orbars knife 10 has afront end 22 from which theblade 15 projects longitudinally and arear end 23. The first orfront bridge 18 has a face 18 a forming one side of ablade clamp 26. Thesecond bridge 19 is the pivot for therocker 12. The third andfourth bridges latch 14. - As also shown in FIGS. 7 and 7A, the
rocker 12 is formed as a two-arm lever with afront part 24 and aback part 25. Thepart 24 is formed with a holding surface 24 a that grips theblade 15 together with the holding surface 18 a. Abump 27 on the surface 18 a fits through a hole 15 a (FIG. 4) in theblade 15 and into aseat 28 on the surface 24 a to solidly lock theblade 15 in place when therocker 12 is in the illustrated closed position. Centrally therocker 12 has acutout 51 that fits on thepivot bridge 19 and rearward of thiscutout 51 it has ashort arm 25 a and along arm 25 b having inner faces 29 and 30 forming a rearwardly open seat or notch 52. Thelong arm 25 b has at its rear end a wedge-shapedcam bump 39 projecting upward into thenotch 52. Pivoting therocker 12 clockwise as shown in FIG. 7 about thepivot bridge 19 separates the surfaces 18 a and 24 a from each other to allow theblade 15 to be removed and replaced. Atransversely throughgoing hole 49 is provided to reduce the weight of therocker 12. - The
slide 13 as shown in FIG. 8 is formed with a pair of longitudinally extending and oppositely transverselyopen guide grooves complementary guide ridges 31 and 32 (see FIG. 4) formed on inner faces of the handle bars is 16 and 17 so that thisslide 13 can shift limitedly longitudinally in thehandle 11. It has atop surface 35 formed with a plurality of crosswise ridges or bumps 35 a that facilitate such sliding and that project slightly above the adjacent surfaces of thehandle 11. At its front end it is formed with a pair of transversely and longitudinally offsetportions angled web 38 and adapted to fit into thenotch 52 and press against theinner surfaces arms rocker 12. When in this forward retaining position, theslide 13 locks therocker 12 against counterclockwise rotation into an unillustrated open position with the surfaces 18 a and 24 a spaced from each other sufficiently to allow theblade 15 to be switched. - Displacement of the
slide 13 rearward in the direction of arrow 42 (FIG. 2) through a stroke S into an unillustrated rear position moves the very front end of theportion 37 slightly forward of the rear end of theshort arm 25 a. Such rearward displacement causes an angledlower face 40 of theweb 38 to engage theinner surface 30 of thearm 25 b and then thebump 39 to pivot therocker 12 downward as shown byarrow 43, toward the open position. Thus to change ablade 15, the user need merely shift theslide 13 rearward with his/her thumb so as to open theclamp 26. To lock in the new blade, theslide 13 is shifted forward indirection 41, thereby pivoting theclamp 26 back indirection 44 to the illustrated closed position. - In order to prevent the slide3 from pulling wholly out of the
notch 52, it butts against front faces 50 (FIG. 2) of thelatch 14. Thislatch 14 is basically J-shaped and has on its short leg a ridge orbarb 47 so that it can be snapped in place over the rearmost orfourth bridge 21 and on its other long leg an offsetfront end 45 that fits in thethird bridge 20. Aweb 46 joining the short and long legs fits complementarily over the rear edge of thebridge 21 with thebarb 47 engaging afront edge 48 of thisbridge 21. - The
knife 10 can be assembled and disassembled easily without tools. To start with theslide 13 is snapped into place between theridges face 48 of theweb 21. Then therocker 12 is hooked by itspivot cutout 51 over theweb 19 and is pivoted down so itsnotch 52 is aligned with thefront end 37 of theslide 13. Theslide 13 is then slid forward, and thelatch 14 is snapped into position on therearmost bridge 21. - Disassembly is done in the reverse order. More specifically the short leg of the
latch 14 is pried up so thelatch 14 can be slipped back off thebridge 21. Theslide 13 is then shifted back so it pulls completely out of thenotch 52, whereupon therocker 12 is pivoted and unhooked from thebridge 19. Then theslide 13 is simply pried out of thehandle 11. - While the description above refers to a very slim deburring tool, of course the instant invention covers other tools having replaceable but fixedly mounted blades. A larger utility-knife blade or a special duty blade, e.g. a carpet hook, could be held in a somewhat fatter handle.
